Patent JP-H09164141-A (JP)
Title: Ultrasonic doppler diagnostic apparatus
Inventor: KOBAYASHI MASAO
IPC: G01B17/00
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To keep the display content of a Doppler image even if the transmission frequency of ultrasonic waves is changed and to make the cut-off frequency of a low-pass removing filter variable in connection with a change in the transmission frequency of ultrasonic waves. SOLUTION: A frequency divider 16 divides transmission frequency f0 by (n) to form transmission repeating frequency fpr . By this method, ultrasonic waves with transmission frequency f0 are emitted into a living body at the cycle of the transmission repeating frequency fpr by a probe 11. A receiving signal passes through a filter A24 to be sent to a quantizing circuit 26 and sampling is performed by the same frequency as the transmission repeating frequency fpr . The cut-off frequency of a low-pass cut-off digital filter B28 is proportional to sampling frequency. Since the transmission repeating frequency fpr is proportional to the transmission frequency f0 , a speed display range can be kept regardless of the transmission frequency f0 . Further, the cut-off frequency of the filter B can be set in proportion to the transmission frequency f0 .

Title: Lane mark recognizing device, lane class kind judging device, vehicle traveling controller and recording medium
Inventor: OIKE TATSUYA
IPC: G05D1/02
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a technique for judging whether components of a string model have converged to a lane mark. SOLUTION: After the string model is converged as a whole (S130), judgment of coincidence is performed to string components. The judgment of coincidence is performed by 'a specified evaluation formula, based on image featured values of the lane mark' as positional energy E/gravity F>A and the positional energy E>B by defining A, B as constants (S150). Since the evaluation formula is not satisfied at parts other than surroundings of the lane mark, the string components for satisfying the evaluation formula are judged to coincide with the lane mark. When the string components are judged as to whether they have converged into the lane mark, calculation of recognized distance (S190) and recognition of lane mark type (S200), etc., are performed.

Title: Device to melt snow around switching point in track
Inventor: SAWAMURA KAZUNORI
IPC: E01C11/26
Filed: 1989-12-14
Abstract: PURPOSE:To melt snow fallen around a railroad track continuously in high efficiency by laying heat pipes on both sides of a heat source duct laid in the track, and by supplying warm and vapor from a heat source device to heat- receiving members of the heat pipes. CONSTITUTION:A heat source duct 3 is embedded across a tack 5 in the vicinity of a switching point 7 in a railroad roadbed and warm air is supplied there from a heat source 2. A plurality of heat pipes 1 are placed at specified intervals on the track 5 on both sides of the heat source duct 3. Heat-receiving members 11 in the heat pipes 1 that are thrusted into the heat source duct 3 are warmed with warm air or vapor from the heat source 2, and working fluid 111 enclosed in the pipes is vapored and the vapor is led to a radiator 12. During such process, the vapor inside the heat pipes 1 condenses and liquefies by radiation and the liquid returns to the heat-receiving members 11. Thereby the heat pipes themselves become a heat source, serving to melt snow 6 fallen around the track and, at the same time, efficiency in snow-melting can be improved.

Title: Switching-mode power-supply apparatus with variable start-up frequency circuit
Inventor: CHUNG-HSING WU
IPC: H02M3/28
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to have a fast start-up time over a wide input- voltage range by a method wherein the apparatus is started up at a low oscillation frequency in the case of a high input voltage and the apparatus is started up at an ordinary oscillation frequency in the case of a low input voltage. SOLUTION: In the case of a high input voltage, a transistor T2 is turned on through a resistor R24, and a current which flows to a capacitor C12 through a resistor R51 and the transistor T2 from a capacitor C26 reduces an oscillation frequency in a start-up phase only while the capacitor C12 is discharged. In addition, in an ordinary mode, a feedback winding W2 generates a voltage required in a drive stage D through a supply voltage Vcc , a resistor R10 and the pin 15 of an integrated circuit IP1. Then, the duty cycle of a PWM signal V2 is controlled by an error signal. At this time, the charging operation of a capacitor C14 decides the start-up time. In the case of a low input voltage, the value of the capacitor C14 is reduced down to a value required for the stable operation of the integrated circuit IR1.

Abstract: PROBLEM TO BE SOLVED: To improve productivity, quality reliability and safety by winding an amorphous alloy foil as a magnetic core uniformly and fast from the winding start to the winding end. SOLUTION: The end portion of an amorphous alloy foil 51 supplied from a foil supply unit is put between a pair of core halves 3.
